I use MS 11 and MailWasherPro. Some emails showup in MWP but do not showup in TB. I have checked all the mail boxes and they are not blackmailed etc.

Wondering if I need to adjust settings in TB?

Please help me sort out my Thunderbird I have 2 computers, emails work on one and not the other I have checked the settings and both are the same and have same Virus protections on both computers I am at a loss to find out why please

I posted a similar question earlier, and although I never got any useful advice, the problem of random emails disappearing from my PC seems to have resolved itself after a week or so. However the problem has now turned up again, but this time on my husband's PC (both PCs are running Windows 10 and latest version of Thunderbird). None of the three accounts on his PC is receiving emails, although Thunderbird correctly enters the number of 'unread' emails and updates it when more arrive. The emails do arrive on my own PC and on my Apple devices (all of these also receive email for all three Thunderbird accounts), but they do not arrive on his desktop PC: the only way he can read his email at present is for me to forward it from the inbox on one of my devices to his Gmail account. If I do this, Tbird seems to recognize that the email has been opened and read, and on his PC the number of unread messages is updated (it might be worth noting that the number appears in grey, not blue as usual). He is able to send new emails from Tbird, although of course he is unable to reply to the messages that are not displayed there. It is particularly annoying because most of the missing mail is either business related or updates on medical appointments, etc.

I really cannot understand this problem, and am probably not explaining it very well. Thunderbird on his PC seems to recognize that new emails are coming in to all three accounts, because the number of unread messages updates, but the messages themselves are not being displayed (I've looked for them in junk, deleted, etc., but no luck). There are no filters set up to redirect things (except a few to send scams to junk). And all the emails are coming in fine to all three accounts on my PC, as well as my Apple devices & our server's webmail function.

If anyone can help, we would be very grateful. We are long-time Thunderbird users, and would hate to have to give it up and learn something new. Many thanks.

Thanx for initial reply to my help request ...

My problem with Thunderbird downloading my Yahoo.com e-mails continue.

I've changed Yahoo.com passwords in the past with no problems. Thunderbird seems to have changed & become more complicated. I can't find the app password Generator for Thunderbird, but I'm able to see my Yahoo Password & the Oauth2 security protocol etc

So how in the heck can I get Thunderbird to work properly? And download my my messages into TB as it has done for years.

Is there any indication on an email that I've already forwarded it? i.e., How can I tell if I already forwarded and email, and to whom? I guess I could look in my sent folder, but that's quite cumbersome. - Thanks

Thamkyou. A year ago after decades of thunderbird, I was required to sign into email everytime I went to or back to email. I tried to find answers online and w/ISP. ISP said it was email problem. 2. Every year or 2, my email stops. When I call, the say it is thunderbird until I ask to verify ports. They come up with different ports. They say I need to use map instead of pop. I used pop as they first stated to use and then they wanted me to use imap. After trying ports they choose, it was ok for a while. I started out w/ assurance, name change to domain.com, then web.com and now NS. They could not find my email in th past and then stated it was on a different server. Which I think means there was a missing link. I am a user, not a programmer. I created 450 web pages with DW and was amazed they all passed online, still do. Now, with NS, email is stopped. They want me to use web mail and I do no. They stated to use outlook. I prefer thunderbird because I was told decades ago that thunderbird and Netscape were the best because they keep it simple W/O excessive links cluttering up the home. So, now my email shows that there is email commit I need the trailer on bottom of page but it does not show up. So, I did get a message earlier Wed that thunderbird rejected "imap". ISP said not their problem. I am 83, disabled vet and have tried evey combination of ports, pop, imap for days and hours with no avail. So you are right. I am an idiot. My bank, cell phone co,, utilities and others recognize me by my email. I have many directories of frequent contacts from people I have deal with. I also save trash because it is a source of records. When it works, it is great.
